Booking Change

Hi all
I have a quick query.
I have a forthcoming ex-eu booking. I received notice of a change today in the booking. When I checked it had an updated comment
NON END/PENALTIES APPLY-BG:BA NON END / PENALTIES APPLY - BG:BA NON END/PENALTIES APPLY - BG:BA.
I googled it to see I could find out what it was, but not really clear.
Anyone know what this means?
Thanks

If you go on Flyertalk you'll see a lot of people have had similar notifications - I've had three today! Nothing to worry about, seems to affect airlines that use the Amadeus booking system (including BA) so presumably some new system has come into effect that shows coded ticket restrictions that didn't previously show up.

Thanks Gumshoe for the response. Nothing to worry about then.

I got some of those this morning for BA flights I am taking on Thursday and Friday.

I just assumed it was something to do with how soon the flight is.
